RESUMO

UNLABELLED: Newborns (NB) represent a surgical challenge for the surgeon due to their physiological characteristics and reduced surgical spaces. During the last decade, minimally invasive surgery (MIS) has been adopted as a treatment for this group of patients. OBJECTIVE: To report our experiences of MIS on NB weighing less than 2,500 grams. PATIENTS AND METHOD: A retrospective descriptive study was conducted analyzing the records of newborns weighing less than 2,500 g and subjected to MIS between April, 2009 and 2012. No patients were excluded. RESULTS: 25 newborns participated on this study; among the treated conditions, congenital diaphragmatic hernia (1), Esophageal Atresia (4 complete repairs and 2 fistula ligation), duodenal obstruction (7), Gastroesophageal reflux disease (6 Nissen procedures, 4 including gastrostomy), Laparoscopic gastrostomy (2) Intestinal obstruction (two bowel resections, end to end anastomosis), and Hypertrophic pyloric stenosis (1). The average weight was 1,920 g (1,300-2,490 g) and 10 of the infants were preterm newborns. 3 mm instruments were used, 5 mm optic 30°. Neither intraoperative complications nor conversions were observed. A patient with tracheoesophageal atresia presented a fistula at the site of anastomosis with spontaneous resolution. CONCLUSIONS: MIS has revolutionized surgery, resulting in less intestinal adhesions, postoperative pain, shorter hospital stays and better aesthetic results. Due to the availability of smaller size materials, these procedures could be performed safely.

RESUMO

Introduction: Esophageal atresia (EA) is the interruption of the continuity of the esophagus, with or without persistent communication with the trachea. Recent advances in surgical techniques have made possible correction with minimally invasive surgery (MIS). Objective: To evaluate the management of thoracoscopic technique in the treatment of EA. Patients and Method: Retrospective analysis of medical records in two centers was carried out between 2007 and 2012. Variables such as gestational age, gender, weight, type of esophageal atresia, malformations, surgery and postoperative complications were recorded. Results: Twenty patients, 15 of them with type III EA, 4 with type I and one unclassifiable, were part of the study. 13 patients underwent ligation, cut of tracheoesophageal fistula and end to end anastomosis. Two underwent laparoscopic gastrostomy and fistula ligation. One patient required conversion and underwent esophagostomy plus gastrostomy. 4 patients without fistula required laparoscopic gastrostomy and aspiration of the proximal esophagus to be able to perform esophageal anastomosis. In the postoperative period, pleural drainage and a transanastomotic feeding tube were installed. Seven patients required esophageal dilations and 4 patients developed stenosis due to reflux. Two had recurrent fistula, one with spontaneous resolution and another with endoscopic resolution. Three children died: two of them due to pathologies not related to surgery and one as a result of limitation of therapeutic effort after fistula patency. Discussion: Esophageal atresia repair with MIS is a safe and effective option with excellent exposure and visualization of anatomic landmarks and little associated morbidity.

Introducción: Atresia esofágica (AE) es la interrupción de la continuidad del esófago, con o sin comunicación con la tráquea. Los avances en cirugía han permitido su corrección con cirugía mínimamente invasiva (CMI). Objetivo: Evaluar el manejo toracoscópico en AE. Pacientes y Método: Revisión retrospectiva de fichas de 2 centros entre 2007 y 2012. Se registraron variables como edad gestacional, sexo, peso, tipo de atresia esofágica, malformaciones, cirugías y complicaciones postquirúrgicas. Resultados: Veinte pacientes, 15 tipo III, 4 tipo I y uno no clasificable. En 13 pacientes se realizó ligadura, sección de fístula tráqueo-esofágica y anastomosis término-terminal. Dos fueron sometidos a gastrostomía laparoscópica más ligadura de fístula. Un paciente requirió conversión y se realizó esofagostomía más gastrostomía. En 4 pacientes sin fístula, se realizó gastrostomía laparoscópica y aspiración del esófago proximal hasta lograr realizar la anastomosis esofágica. En el post-operatorio se instaló drenaje pleural y sonda trans-anastomótica. Siete pacientes requirieron dilataciones esofágicas y 4 desarrollaron estenosis por reflujo. Dos presentaron fístula recidivada, uno con resolución espontánea y el segundo de resolución endoscópica. Tres niños fallecieron: dos por patologías no relacionadas con la cirugía y uno con limitación de esfuerzo terapéutico con repermeabilización de fístula. Discusión: La atresia esofágica reparada con CMI es una opción segura y efectiva en esta serie, permitiendo excelente exposición y visualización de reparos anatómicos, con poca morbilidad asociada.

El Recién Nacido (RN) quirúrgico representa un reto para el cirujano, por sus características fisiológicas y espacios quirúrgicos reducidos. Durante la última década se incorporó la cirugía mínimamente invasiva (CMI) en este grupo de pacientes. Objetivo: Reportar nuestra experiencia en CMI en RN < 2.500 g. Pacientes y Método: Estudio descriptivo retrospectivo, se analizaron fichas de RN < 2.500 g sometidos a CMI entre abril de 2009 y abril de 2012. No se excluyeron pacientes. Resultados: Se incluyeron 25 RN. Las patologías resueltas fueron: Hernia diafragmática congénita (1), Atresia Esofágica (4 reparaciones completas, 2 ligaduras de fístula), Obstrucción Duodenal (7), Reflujo Gastro-esofágico (6 operaciones de Nissen; 4 con gastrostomía), gastrostomía laparoscópica (2), Obstrucción Intestinal (2 resecciones intestinales, anastomosis término-terminal), Estenosis Hipertrófica del Píloro (1). Peso promedio: 1.920 gr (1.300-2.490 gr), 10 RN pre-término. Se utilizó instrumental de 3 milímetros (mm), óptica de 5 mm de 30°. No se presentaron complicaciones intra-operatorias, ni conversión. Un paciente con atresia tráqueo-esofágica, presentó una fístula en el sitio de anastomosis con resolución espontánea. Conclusiones: La CMI ha revolucionado la cirugía, manifestándose en disminución de adherencias intestinales, menor dolor postoperatorio, estadías hospitalarias más cortas y mejor resultado estético. Con el desarrollo material de menor tamaño, estos procedimientos se pudieron realizar en forma segura en esta serie.

RESUMO

Introduction: Necrotizing Enterocolitis (NE) is the most frequent gastrointestinal emergency among newborns (NB). Thirty percent of them require surgical treatment, with resection of the damaged intestinal segment and stoma formation. In some cases, primary resection and anastomosis can be considered. Objective: To review the use of primary anastomosis on NE in 2 pediatric centers, one public hospital and one private clinic. Patients and Method: A retrospective, descriptive study of all NB with NE managed with primary anastomosis at Hospital Exequiel González Cortés y Clínica Las Condes between December 2004 and december 2009. The population was divided into Group A: Unifocal, and Group B: Multifocal intestinal involvement. The following variables were evaluated and compared: gestational age, weight, use of peritoneal drains, characteristics of the resected segment, number of anastomoses, requirement of parenteral nutrition, postoperatory complications. Results: Sixty NB were surgically repaired with primary anastomosis. 12 percent presented birth weight <1.000grams, 22 percent between 1000-1500 grams. In 18 patients 2 anastomoses were performed in different intestinal segments. Postoperatory complications included wound infection in 3 cases and dehiscence of the anastomosis in 1 case. 7 percent evolved with short loop syndrome. Mortality was 11,6 percent, secondary to sepsis. Conclusions: In this experience, Primary Anastomosis in NE appears to be a safe option, with low morbimortality despite the age, weight, IP contamination or extension of the disease.

Introducción: Enterocolitis Necrotizante (ECN) es la emergencia gastrointestinal más común del recién nacido (RN), 30 por ciento requiere tratamiento quirúrgico, con resección del segmento intestinal dañado, realizando luego una ostomía en la mayoría. En recientes casos la resección intestinal y anastomosis primaria han sido reportados en forma exitosa. Objetivo: Evaluar la experiencia del manejo con anastomosis primaria en ECN en 2 centros pediátricos, un Hospital público y una Clínica privada. Pacientes y Método: Estudio descriptivo retrospectivo. Se incluyó a RN del Hospital Exequiel González Cortés y Clínica Las Condes con ECN manejados con anastomosis primaria, entre diciembre de 2004 y diciembre de 2009. Se dividieron en Grupo A: Unifocal; Grupo B: Compromiso intestinal multifocal. Se comparó entre ambos grupos: edad gestacional, peso, utilización de drenajes peritoneales, características del segmento resecado, número de anastomosis, requerimientos de nutrición parenteral, complicaciones postoperatorias. Resultados: Se sometió a cirugía con anastomosis primaria a 60 recién nacidos. El peso de nacimiento fue < 1 000 g en el 12 por ciento, 1 000-1 500 g el 22 por ciento, y el resto >1 500 g. En 18 pacientes del grupo B se realizaron 2 anastomosis en segmentos intestinales diferentes. Las complicaciones postoperatorias fueron infección de herida operatoria (n:3) y dehiscencia de anastomosis (n:1). Un 7 por ciento evolucionó con síndrome de intestino corto. La mortalidad fue 11,6 por ciento, en todos los casos secundaria a sepsis. Conclusiones: En esta experiencia la Anastomosis Primaria en ECN aparece como una opción segura, con baja morbimortalidad independiente de la edad, peso, contaminación intraperitoneal o extensión de la enfermedad.
